this is going to be long winded , pls bear with me. i've hooked up my hercules game theater sound card up to my home theater setup , the problem i'm getting is a loud hum from my speakers in the h/t. i've tried plugging the computer into the same curcuit as the h/t but the hum is still present , made sure the patch cable is nowhere near any power source. the odd thing is that when i turn off the computer the hum is still heard in the speakers , but when i unplug the computer and the monitor from the wall the hum goes down to almost nothing. i tried plugging the monitor and computer into another curcuit together still the hum. any solutions that i can try , i've asked different people and one suggests a ground loop isolator , others say better quality cables to the h/t and each other say the others solution won't fix it so i'm really stumped. after reading up on hums on the web it seems to be a ground loop isolator that will fix it up but i'm really stumped now. thanks gord
